The purpose of this study was to explore the differences in time perspective by socio-demographic variables and to investigate the effect of time perspective on time management and life satisfaction for college students. Questionnaires including time perspective, time management, and life satisfaction scales were used for this study. The survey data from 382 college students were analyzed by frequency, percentage, mean, standard deviation, t-test, ANOVA, Duncan test, Pearson's correlation analysis, and stepwise regression. The time perspective, composed of four factors future insensibility and present, past, and future orientation, differed according to the sex, academic grade, and specialty of the college students. The time perspective of the college students and the socioeconomic status of their households were investigated as effective variables on time management and life satisfaction. Based on these results, the implications for research and policy on the time perspective of college students were discussed.

Concurrent construction offers considerable improvement for shorten the project duration of its production process. Therefore, standardized concurrent construction is widely applied in building construction projects. However, resources planning for standardized concurrent construction project is manually developed by construction manager. This practice is not effective since it is time-consuming and error-prone for managers to identify all project-specific information, distinguish different activity-resource types, interpret these types and analyze how they affect resource allocated on an ad hoc basis. Therefore, this research investigates the opportunity for leveraging activity modeling to enable automated resource planning for standardized concurrent construction during project development, with identifying the characteristics of construction activities under standardized concurrent planning and determining the activity-resources types that affects resource planning. Both will function as a basis for modeling these construction activities in a computer-interpretable manner and for automation in resource planning.

To enhance tracking efficiency, a target-tracking filter with a resource management algorithm is required. One of the resource management algorithms chooses or evaluates the proper sampling time using cost functions which are related to the target tracking filter. We propose a resource management algorithm for bearing only tracking environments. Since the tracking performance depends on the system observability, the bearing-only tracking is one of challenging target-tracking fields. The proposed algorithm provides the adaptive sampling time using the variation rate of the error covariance matrix from the target-tracking filter. The simulation verifies the efficiency performance of the proposed algorithm.

The purpose of this study was to explore the effects of socio-demographic variables on time management and to investigate the effects of time management on self-efficacy and academic achievement in college students. The data were collected from 382 college students through questionnaire surveys and analyzed using frequency, percentile, and regression analysis with the SPSS program. College students' time management behavior was influenced by the social status of their families and by their participation in time management education. There were differences in variables affecting time management according to its sub-areas (planning, regular habits, and goal-oriented behavior). Planning was influenced by the students' majors and by their participation in time management education. Regular habits were influenced by the students' genders and their families' social status. No variables affected goal-oriented behavior. Time management (especially planning and goal-oriented behavior) and gender had strong effects on self-efficacy, and male students showed more self-efficacious behavior than their female counterparts. Time management (especially planning and regular habits) and gender had strong effects on academic achievement, and female students received higher academic grades than their male counterparts. Based on these results, time management was confirmed as an influential element in self-efficacy and academic achievement. Planning and goal-oriented behavior particularly influenced self-efficacy, and planning and regular habits particularly influenced academic achievement.

This study focuses on time management behavior, which differs in (1) the characteristics of schools and (2) the experience of education about time management. Also, this study examines the effect of time management behavior on life satisfaction of vocational and non-vocational high school students, and also those who attend life-long education schools. The study sample consists of 367 teen-age high school students in Seoul. The result of this study demonstrates that the experience of education about time management has a great effect on time management behavior. Students experiencing education about time management have higher scores in time management behavior than those who lack such experience. It also shows a close relationship between time management behavior and life satisfaction in non-vocational high school students and those attending life-long education schools.

The purpose of this study is to examine the allocation of time between work and leisure by the rural elderly in Korea. The data used for this study are collected from fm households during the peak ($17^{th}\;to\;30^{th}$ June) and off-peak ($28^{th}$ November to $10^{th}$ December) farming seasons of 2005 using time diary. The sample for this study consists of 120 elderly over 65 years old living in rural area in eight provinces. The major findings are as follows. (1) The time spent of farm work by rural elderly in much longer than average work hours of elderly in general regardless of farming season. The indicates that the elderly farmers are the sustaining forces of agriculture as the urban industrial sector absorbs the younger labor force rural area. (2) There are significant differences in the work time(including form work, housework, and farm work plus house work) by gender, age, education, marital status, living arrangements. (3) The rural elderly spends less time in leisure compared to the elderly in general even during the off-peak season. (4) Especially during the peak season, time allocation between work and leisure by the rural elderly is heavily skewed, resulting in an inadequate amount of time for reproduction of labor. (5) There is only significant age difference in the amount leisure time regardless of farming season. (6) Male elderly farmers work approximately 30 minutes to 1 hour longer on farm than the females do, but the total work time (farm work plus housework) of female elderly is longer than that of the male elderly. There is no significant gender difference in the amount of leisure time during the peak season, whereas the men have more leisure than the women during the off-peak season. To conclude, the gender differences in time allocation among the rural elderly are minimal. However, the rural elderly of both genders suffers from excessive work hours and heavy workload compared to the urban counterpart.

The purposes of this study were firstly to reveal the sub-dimensions of time management behaviors and secondly to group workers by time management behaviors. The major findings of this study were as follows. (1)Factor analysis of the 36 items on the time management behaviors instrument revealed three components: factor planning, relations-intention, and urgency. (2)Workers were categorized into four types by the level of those three factors of time management behaviors: 'accomplishment type'($28.31\%$), 'chronic-urgency type'($24.39\%$), 'valuing-job type'($23.73\%$) and 'valuing-human relations type'($23.57\%$). (3)The accomplishment type gained the highest points on the time management satisfaction score, and the level of important${\cdot}$non-urgencies was the highest score, indicating that the accomplishment type had good time management. However, the level of unimportant${\cdot}$urgencies was the highest score. Therefore, this type should try to reduce the level of unimportant${\cdot}$urgencies.
